Abstract: It is difficult to explain an origin of all celestial bodies of the Solar system by smooth evolution of the protoplanet cloud. The alternative is the hypothesis of the explosive origin of some bodies. The nuclear explosion in active layer (particles of uranium and thorium oxides, weighed in liquid iron at a planer core) might take place at collision of the protoplanet with an asteroid. Subsequent fragmentation of the planet in conditions of gravitation is numerically simulated. It was found that the structure and composition of fragments may be determined by the cumulative jet, going from a planetary core to its surface for small enough initial velocity of protoplanet rotation. The origin of Io may be so explained, for example. Separation of the great mass of the stone-silicate shell of the planet and the generation of satellites like the Moon occurs at the great enough velocity of rotation
